Abstract
Body surface reliefs of ten young Japanese women in standing and squatting positions were measured using the Grating Projection System for Profiling (GRASP method) and analyzed. The body area investigated was the back right half of the torso from the bottom of the bust to the thigh, on which five vertical and ten horizontal lines were marked as references. The body area was divided into six parts as determined by surface deformations which accompanied changes from standing to squatting positions. The medial parts from the scapular line around waist and abdomen line expanded about 50% in vertical length and nearly 100% around the gluteal fold. The vertical length of lateral part around the hip line contracted about 25%. The body area showed little change in horizontal length. Based on the results of this study, eases were added to the slacks pattern. The slacks were then tested on two women. The added eases were found to be large enough and appropriate in location to allow free movements of the hip joints in both standing and squatting positions.
